    This video was everything I wanted! I have a vague idea of everything in here and just needed a refresher on the actual practical use of everything. Thank you!

    Thanks, great video! How does the metal stirrer help the process? I usually leave the tank without it being stirred the whole time, would love to know how stirring it helps as I may try that! Thanks so much in advance.

    • @bradywells1293
      @bradywells1293 6 лет назад +4

      The liquid can make its way into the pipette and cause contamination to the next sample(s) you use it for or it can just damage the sensitivity of the pipette by getting stuff gunked up inside.

    Great tutorial! But,
    13:58 you didn't depict the amplification tree (usually the secondary is polyclonal), so there's multiple secondaries binding to the primary to 'blow up' your signal from the HRP reaction.
    Besides that: *great channel* here, man! Why did you stop though :(
    Just as I'm discovering all these helpful channels... I even made a Top 10 channel overview on my own channel, and I'm planning on making a second one with 'smaller channels' like this one. All good stuff for Biomedical/Life Science students!

      I'm re-acquainting myself with this stuff after years of not being in a wet lab. Thanks for this detail and the overview vid on your channel. Polyclonal secondary antibodies sounds clever and makes a lot of sense.

    Can the primary and secondary antibodies be diluted in the 5% non-fat milk and then each incubated with the membrane? Rather than doing the blocking step as its on whole step?

    • @Biomeducated
      @Biomeducated 5 лет назад +1

      You mean put everything in at once at the same time to reduce protocol time? Not with the blocking step for sure, but perhaps you can premix primary and secondary at equimolar concentrations, then you are sure that no excess secondary will deplete your primary if you wash afterwards. Then again, you would loose your 'amplification tree' which could results in not seeing a good signal. Usually the secondary antibody is a polyclonal so multiple HRP-conjugated antibodies bind to the Fc-part of your primary, needed to amplify your signal. I would just stay with the sequential protocol.
      Or maybe I misread your question (just realized I think): yes, your antibodies should be diluted in the same solution as the blocking, but usually it's more diluted than for the blocking. So if you block with 5%, you stain in 1% or 0.5%. Note that some protocols recommend using BSA as blocking and for dilution...

    • @МаринаЗеленюк-р3ч

      Usually you should to incubate the membrane with bloaking solution during 1 hour. Then you should wash 3 times and incubate with primary Ab diluted in 5% milk PBS overnight. Then you schould wash 3 times and incubate with secondary Ab diluted in 5% milk PBS during 1 hour. Wash 3 times and make a picture.
